9cffd3d1d4 refactor templater: Add explicit note about empty-rs warnings
Due to an interesting combination of an error not being handled and Go
initialising everything with what it thinks should be the default,
non-existent resource sets have been gracefully handled already.

This makes this accidental fix explicit.

Fixes #90

b20bc5f57a fix templater: Don't template default.yml files
After the change from #84 default variable files with the '.yml'
extension got templated as resource set templates accidentally.

This resolves the issue by moving the list reserved default file names
to a common place and reusing it in both the templater and context pkg.

This fixes #85

a7781b169d fix templater: Ignore slash-suffixes on includes/excludes
To prevent situations where a shell auto-appends a slash to an
include/exclude specification on the CLI, trailing slashes in those
string lists are now trimmed.

This fixes #54

This also fixes #56

32ca64c50a feat templater: Warn if no valid resource sets are included
After filtering resource sets, check whether any resource sets "survived".

Otherwise it can be assumed that the user specified invalid exclude/include
combinations and should be warned about that.

Fixes #35

3b0f41e71d feat templater: Fail if values are missing
Golang's template package now has an option for failing if template variables
are missing: https://golang.org/pkg/text/template/#Template.Option

This updates the templater code to make use of that option and return the
errors encountered during templating.

This fixes #1

2f6e008121 feat templater: Add 'pass' lookup function
This introduces support for looking up secret values in the 'pass' command line
tool (https://www.passwordstore.org/).

Values like passwords can be interpolated from pass and even more complex
structures like certificates for Kubernetes Secrets can be retrieved and base64-
encoded as necessary.

Fixes #2

4e8223ef34 feat context: Add support for resource set collections
A resource set collection is a resource set with an addition 'include' array
configured. It is a short-hand for importing multiple resource sets from the
same folder and for excluding/including them as a group.

See https://github.com/tazjin/kontemplate/issues/9 for more information.

Closes #9

8e08a282eb feat templater: Add ability to exclude resource sets
* renamed --limit to --include (-i)
* added --exclude (-e)

Kontemplate users can now explicitly include and exclude certain resource sets.
Excludes always override includes.

Closes #11

25f2a1616c feat template: Add additional template functions
This adds the Go template functions from [sprig][] as well as a custom `json`
function that can interpolate any data as a JSON object - very useful for adding
arrays of data in JSON format into a variable:

```
certificateDomains:
  - oslo.pub
  - tazj.in

annotations:
  acme/certificate: {{ .certificateDomains | json }}

annotations:
  acme/certificate: ["oslo.pub", "tazj.in"]
```

7ac63613fb feat main: Add proper CLI support
Adds a basic CLI structure with a single "run" command that takes a --file (-f)
and --limit (-l) flag.

--limit can be used to only output certain resource sets.
